Right now, the most sensitive pregnancy test on the market is the First Response Digital Pregnancy Test. It can detect the hCG levels in your body as many as six days early. Studies confirm that this test can detect hCG levels when they are as low as 6.5 mIU/ml.
HCG is the hormone that  pregnancy tests  detect. HCG increases to a peak at around 12 weeks. It has mild thyroid stimulating effects and, as a result, can cause some symptoms of hyperthyroidism. HCG is in part responsible for the nausea during the first trimester. In situations of multiple pregnancies (twins, triplets) HCG levels are even higher, and symptoms can be more pronounced. Temporary subclinical (no apparent symptoms) hyperthyroidism occurs in 10-20% of normal pregnant women during this period, and these women typically do not require treatment.
